Dual G5 freezing on first boot

[iLucas]

Hello all,
Lately my G5 1.8 dual has been freezing on first boot and i'm not sure why.
If i hold the power button to shut it down, then reboot it, it works great until i shut it down again. Then it freezes on first boot again. It's been doing this for awhile and i think it could be software issues, but im not sure,
what do you think?

Have you tried zapping the PRAM? Thats what I normally try when I have odd startup/reboot issues. I can recall that once fixing an issue I had with my Sawtooth. It would allow me to reboot but not shutdown. I would select shutdown in the Apple menu and just as it seemed like it was about to shutdown it would start the reboot process. I zapped the PRAM and all was well again.

come to think of it, i haven't zapped PRAM for awhile now so that could do the trick. I'll check back with results after i get home.

thanks zen

So far so good.
Zapped PRAM and on first boot it never froze.

That one day of not freezing on first boot was luck i guess.
Since then it's been something new everyday. Yesterday it hung on the blue screen on first boot and it worked on second boot. Today it gave me a kernal panic on first boot with a bunch of text on screen, second time it worked..

what is the deal with it not working on first boot?

Found my solution!
I had a logitech z 340 speaker system plugged into it and since unplugging it, the G5 has not gave me any problems. Not sure how the speaker system was giving it problems though
